I have an IBM Optical 4 button USB mouse, and I have a problem.  After about
2 hours of contstant use, the mouse seems to go dead, as in no more power is
going to it.  The red scanner light at the bottom goes out, the pretty blue
mouse wheel light goes out, and the computer stops responding to the mouse.
Now, it seems obviouse to me that the power to the mouse is being cut off
somewhere in my machine, probably the USB port is going to sleep or
something.  I cannot seem to find anywhere in my bios a setting to keep the
USB from sleeping, if indeed that is the source of my problem.  I am just
curious to know if the problem is with this mouse, or is with my machine.  I
have the IBM mouse model #MO27FO, and an ECS k73ta motherboard, and the
factory usb ports that come with it, and I am running Win 98 SE.  If anyone
has any ideas as to what the source of my problem could be, I would really
appreciate it.
(Note, I have tried the adapter that came with the mouse, to convert it to
standard PS2 mouse, but then I lose functionality of the fourth mouse
button, and the mouse wheel doesnt really work right in many applications,
mainly games, plus the nice control panel which gives me oh so much
functionality for the mouse reverts to the windows standard mouse control
panel.)
HELP!
